Lisa Wilkinson to release new book exploring her time at Channel 9

Lisa Wilkinson will release a new memoir exploring her time at Channel 9, nearly four years to the day since her shock Today show exit.

Lisa Wilkinson is set to release her highly-anticipated memoir It Wasn’t Meant To Be Like This almost four years to the day since her shock Today show exit.

The TV host vowed to leave “no stone unturned” in a social media announcement on Monday and shared the book cover for the first time as she prepares to tell all about her time at Channel 9’s Willoughby studios.

“I’ve been working on something that is very close to my heart over the last couple of years – in fact, when I think about it, I’ve been working on this my entire life,” Wilkinson wrote on Instagram.

“It’s my autobiography, and I’m excited (and just a little bit terrified) to be sharing the cover with you today … In it, I’ve completely opened up on things I’ve never talked about before, not even with some of my closest girlfriends.

“ … I’ve left no stone unturned, particularly when it comes to some of the more public moments you’ve seen in the headlines. Now, you’ll know the truth.”

The book will be published by Harper Collins on October 27.

The memoir will also explore her early career and marriage to author and TV commentator Peter FitzSimons.

Wilkinson, 61, quit the Today show over a pay dispute in 2017 after 10 years and moved to current affairs show The Project on Channel 10 the following year.

Her departure stemmed from her male co-host, Karl Stefanovic, reportedly earning $2 million – double her $1.1 million salary and Channel 9 allegedly refusing to grant her equal pay.

Wilkinson’s initial deal with Channel 10 was reportedly worth $2.3 million, more than double what she was earning at the Nine Network.

Last month, The Australian reported she signed a “lucrative new multi-year deal” with Channel 10 to cement her future with the broadcaster.

Last year, Nine’s Willoughby site was sold to Developer Mirvac in a deal said to be worth around $249 million.

Nine later moved to a new home in North Sydney, where the Today show, A Current Affair, 60 Minutes and Nine News are now broadcast.
